Three paintings played an important role in Lao She's life, namely Wang Xizhi's love for geese, sword dance and Lienv. Lao She saw his father's favorite painting "Wang Xizhi loves geese" when he was a teenager. This is a line drawing, but the characters and stories in it let him know the beauty of a great calligrapher in China. Sword Dance is a gymnastics textbook written by Lao She in cooperation with his classmates. The time is 192 1 year. The collaborator was Yan Bolong, who later became a famous painter in China.
